Gary, Good luck with your choice. I was just looking around my favorites web sites and came upon BTG, Progress, Gold Line, Blue Line and Eibach. I'm sure people here on this forum have used them all. The biggest thing I can recommend is that make sure they say that the springs are "progressive" which means they keep the same characteristics as the OEM springs but allow the PT to sit lower. Look at the write-up on all the springs your thinking about and see how far they drop the cruiser. BTG for example drops the front 1 3/4" and the rear 1 1/2 so your PT will keep the same "rake" (front lower) as it came from the factory. I used the Eibach Pro Kit and it lowered the rear more than the front so the whole car is lowered and straight.
